1.8 Jumper Settings

This section provides instructions on how to configure your motherboard by setting

the jumpers. It also includes the motherboard default settings and your options for

each jumper.

1.8.1 How to set jumpers

You can configure your motherboard to match the needs of your application by set-

ting the jumpers. A jumper is a metal bridge that closes an electrical circuit. It consists

of two metal pins and a small metal clip (often protected by a plastic cover) that slides

over the pins to connect them. To “close” (or turn on) a jumper, you connect the pins

with the clip. To “open” (or turn off) a jumper, you remove the clip. Sometimes a

jumper consists of a set of three pins, labeled 1, 2, and 3. In this case you connect

either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be useful when set-

ting jumpers.

1.8.1.1 CMOS and ME clear (JCMOS1)

The ASMB-585 motherboard contains a jumper that can erase CMOS data and reset

the system BIOS information. Normally this jumper should be set with pins 1-2

closed. If you want to reset the CMOS data, set JCMOS1 to 2-3 closed for just a few

seconds, and then move the jumper back to 1-2 closed. This procedure will reset the

CMOS to its default setting.

1.8.1.2 ME update (JME1)

The ASMB-585 contains a jumper that can update for ME firmware. Normally this

jumper should be set with pin 1-2 closed. If you want to update ME firmware, set

JME1 to 2-3 closed to disable ME for new ME firmware update.
